Specification forming part of Lett To, all whom t may concern:

n Beit knownV that I, JAMES R. MAXWELL, of the city of Cincinnati,county of Hamilton, and

State of Ohio, have inventeda new and useful Improvement inTater-Meters; and I do hereby declare that the following is a full and`enact description thereof, reference being had to the accompanyingdrawings, and to the let ters and figures of reference marked thereonand. made to form part of this specification.

Similar letters and figures referto like parts of the improvement.

lThe nature of the improvement consists in the manner I employ ofcombining and arranging the parts of the meter together, 4which preventsthe settlingof dirt in the apparatus often contained in the Water andcauses the meter to work with ease and certainty.

Toenable others skilled in the art to make and use 'my improvement, Iwill proceed .to describeits construction and operation by re ferringdirect to 'the a Figure 1 represents a'vertical sectional elevation ofthe improvement, and Fig.-2 represents a transverse sectional elevationof the improvement throughthe valve for admitting and discharging waterfrom the meter.

The meter in body consists of a cylindrical circularchamber or cylinder,furnished with a piston that receives a reciprocating motion, whichApiston alternately actuates a valve that admits and discharges a givenquantity of water fromthe meter. v

a all is what I denominate the cylinder 'of the meter, formed byproperly boring and fittingrthe pieces o f metal together and holdingthem with'bolts'.

B represents :the piston,l furnished with guard-plates cc at` its endsto prevent friction by properly guiding the piston B around the'bore.Y L

The operation of the meteris as follows: X. represents theinducting-pipe, and the dis,-

'charge-pipe. 4 and 5.are receivingfopenngs from the valvechest d intothe cylinderchamber a a, and the valve g in form is like an ordinaryslide-valve of a steam-engine, and Works exactly upon' the sameprinciple in receiving water into and discharging it out of thecylinder@ a-. The way the meter is represented now shows the valve g.asdischarging the water fromthe meter through the opening 5, andthemeter is being filled inlits opposite side through the `opening 4, asdrrectedibyV the dart marked The water acts on the. piston Band forcesit' around as the water is drawn outthrough the opening 5' in thevalve-chest until it strikes the end of the valve-rodf, which acts uponthe quadrantpinion J, attached to the shaft fm.; until the rod/n and lois brought just beyond a vertical position. Then the spring P around therod o, by acting on the pin R, causesthe lever' 4and pin K to actuatethe lever'. h, whichismade to' move the valve g 'by acting on the pins3, placed on each side of the valve, after which the piston B is forcedagain to the other side of the meter by the admission of water, and thusalternately forced from one to the other side to keep up the action ofthe meter for receiving, measuring, and dischargingthe water therefrom;Y g y .What I claimas my improvement, and de sire to `secure by LettersPatent, is 4 The arrangement ofthe piston B, with the parts employed formoving the valve g, all ar.

ranged as represented, and for purposes menf tioned in the foregoingspecific-ation.
